WebMay 4, 2024 · Figure 13.5. 2: The wavelength of a single wave is the distance between two consecutive points of similar position (two crests or two troughs) along the wave. Visible light constitutes only one of many types of electromagnetic radiation emitted from the sun and other stars. Scientists differentiate the various types of radiant energy from the ... In the early 1900s, it became apparent that classical mechanics had some major failings. Isaac Newton originally proposed the idea that light came in discrete packets, which he called corpuscles, but the wave-like behavior of many light phenomena quickly led scientists to favor a wave description of electromagnetism. It wasn't until the 1930s that the particle nature of light really began to be widely accepted in physics. The development of quantum mechanics – and it…
7.3: The Light-Dependent Reactions of Photosynthesis
WebJul 4, 2024 · Figure 7.3. 7: A photosystem consists of a light-harvesting complex and a reaction center. Pigments in the light-harvesting complex pass light energy to two special chlorophyll a molecules in the reaction center. The light excites an electron from the chlorophyll a pair, which passes to the primary electron acceptor. WebJan 30, 2024 · These packets of energy can be transmitted over vast distances with no decay in energy or speed.
